This page lists important events in Unda's history. It is intended as a supplement to IU History.
Most calendars were marked from year 0, the year in which the IU was founded. The IU New Year was celebrated on the first day of year 0, and is also the day of the celebration of the foundation of the IU. The calendar is further divided into ten months and six week days, the names of which were formed in anticipation of the standardization of calendars that began when the IU officially formed. The month names were formed by distilling the Ilonan and Tekali words for the numbers from one to ten, and the days of the week were taken almost directly from Tekal, with some orthographic changes for easier pronunciation.
The months in order are: Premsin, Deuz, Rosdrei, Trevier, Infun, Sisech, Setiben, Hacht, Neuve, and Desen.
The days of the week in order are: Enstag, Veitag, Rittag, Fierstag, Funstag, and Sestag.
